Title: Remove dependency on Scalaz

Since we are no longer using non-empty lists and do not make use of any important functionality from Scalaz, but just some syntactic sugar for working with options, I think we can just as well remove the dependency in an effort to keep external dependencies to a minimum – now, the only ones left are those of the JSON library people want to use.
